    CHATS E. Of the Formation of the temporary Set of Teeth. \ \ HEN the Foetus has advanced so far in the organization of its different parts, as to take some determinate form or figure, we may perceive a considerable progress in the prepa- _ ratory steps for the formation of the teeth. As soon as the ossific deposit commences in the cartilagi-, nous parts: of the embryo, both jaws are filled with small membranous sacs; and, inthe anterior parts, we may perceive the rudiments of alveolar processes. In a Foetus of about four months, the jaw bones are dis- tinctly formed; but at this time they only consist of thin grooved bones, having a cavity extending through their whole length.« In the under jaw, anteriorly, this cavity is narrower B and * The description of what takes place in one jaw, will completely exhibit what concerns the formation of the teeth in both; therefore, in order to avoid confusion, I shall refer to the under jaw only.
